Resposta:
a) a = 4, b = -3
b) a = 25, b = -13
c) a = -3, b = -7
d) a = 4, b = 0
e) a = -3, b = 5
f) a = -10, b = 105
f(x) = ax + b
Coef. angular: a
Coef. linear: b
a. y = 4x - 3
a = 4
b = - 3
b. y = - 13 + 25x
a = 25
b = - 13
c. y = - 3x - 7
a = - 3
b = - 7
d. y = 4x
b = 0
e. y = 5 - 3x
b = 5
f. f(x) = - 10x + 105
a = - 10
b = 105
